steel sheet for drahtrahmen stake in wine or fruit

摘要

The stake (1) has a U-shaped cross-section with hooks (3) formed outside on the arms (6) by punching out a hole (17) and bending round the tongues (8) from the steel plate. The tongues have a widened part towards the open hook tip (18) which is opposite a tapered section (22) of the punched hole. The hook can then only be bent so far closed that its tongue is not pressed into the hole and plastic deformation remains slight.
